Cadmium was discovered in 1817 by Fredrich Stromeyer. Cadmium’s name derives from the Greek word "kadmeia" and the Latin word "cadmia". Cadmium’s melting point is at 320.9 °C (594.05 K, 609.62 °F) and its boiling point is at 765.0 °C (1038.15 K, 1409.0 °F).
Top 9 interesting facts about Cadmium
Cadmium is chemically similar to zinc and mercury.
Cadmium is bluish-white, soft, malleable, resistant to corrosion, and ductile metal.
Cadmium is a byproduct of zinc production.
Cadmium’s use is decreased due to its toxicity.
Cadmium is composed of eight naturally occurring isotopes, two of them are naturally radioactive (113-Cd and 116-Cd) and three of them are stable (110-Cd, 111-Cd, and 112-Cd).
Cadmium is a rare metal making up just 0.1 ppm of the Earth’s crust.
Cadmium’s top producers are China, South Korea, and Japan.
Cadmium is used in batteries, electroplating in aircraft industry, and a small amount in nuclear fission and different laboratory experiments.
Cadmium’s use and supply in Europe is restricted due to its dangerous effects on environment and human health.
